Platycephalus Westraliae
''Platycephalus'' is a genus of mostly marine, demersal ray-finned fish belonging to the family Platycephalidae. They are found in the eastern Mediterranean, the Indian Ocean and western Pacific Ocean. Taxonomy ''Platycephalus'' was first proposed as a genus in 1795 by the German physician and naturalist Marcus Elieser Bloch with ''Callionymus indicus'', which had been described in 1748 by Carl Linnaeus from "Asia", as its type species. This genus is classified within the family Playtcephalidae, the flatheads which the 5th edition of ''Fishes of the World'' classifies within the suborder Platycephaloidei in the order Scorpaeniformes. Etymology The genus name ''Platycephalus'' means "flat head" an allusion to the wide flattened head of these fishes which leads to the English common name flathead. Species There are currently 19 recognised species in this genus: * ''Platycephalus angustus'' Steindachner, 1866 (Steindachner's flathead) * ''Platycephalus aurimaculatus ''Platy ...

Ypresian
In the geologic timescale the Ypresian is the oldest age (geology), age or lowest stage (stratigraphy), stratigraphic stage of the Eocene. It spans the time between , is preceded by the Thanetian Age (part of the Paleocene) and is followed by the Eocene Lutetian Age. The Ypresian is consistent with the lower Eocene. Events The Ypresian Age begins during the throes of the Paleocene–Eocene Thermal Maximum (PETM). The Fur Formation in Denmark, the Messel shales in Germany, the Oise amber of France and Cambay amber of India are of this age. The Eocene Okanagan Highlands are an uplands subtropical to temperate series of lakes from the Ypresian. Stratigraphic definition The Ypresian Stage was introduced in scientific literature by Belgium, Belgian geologist André Hubert Dumont in 1850. The Ypresian is named after the Flanders, Flemish city of Ypres in Belgium (spelled ''Ieper'' in Dutch). The definitions of the original stage were totally different from the modern ones.
